I have a pair of first generation Record Ergos. The original hoods were very worn so I bought replacements and removed the originals. They were difficult to remove and I tore them in doing so.
I ran the Ergos through a kerosene bath in the ultrasonic cleaner, flushed with WD-40 and greased the gears. They're ready for new hoods.
I've installed plenty of aero and non-aero brake lever replacement hoods, but no Ergos. If anyone has any experience here I'd love to hear it. With other levers I submerge the new hood in very hot water, then add some dish soap to slide it on from the rear (clamp end) of the lever. However, with the Ergos, the thumb shifter presents a problem.
Thanks in advance.
